Abstract:
The data set comprises high-time resolution meteor wind velocity data from the southern hemisphere Falkland Islands radar (FIR), part of the Super Dual Auroral Radar Network (SuperDARN). The velocities are line-of-sight velocities aligned in the geographic meridional direction (from FIR beam 6, range gate 4). The data cover the interval from 2010 to 2011 inclusive.
Funding was provided by BAS national capability funding. NERC grant NE/R016038/1 - National Capability - Polar Expertise Supporting UK Research.

| Quality: | The meteor wind data are generally of high quality with low errors. See Chisham and Freeman (2013) for full details regarding data processing. | |
| Lineage: | The data are FIR SuperDARN line-of-sight velocity measurements of winds in the mesosphere lower thermosphere (MLT). The data are from the geographic meridional beam 6, range gate 4 (315 km range). The meteor wind data are measured a few hundred km south of the radar site, and the position is only known approximately. Hence the stated location is an approximate measurement location. |

| Data Storage: | The data file is mts_b6_r4.txt. The data file has the following format: (A series of data records of the form...) Doy, Pwr, Vel, SW, Vel_err, SW_err, Freq (where... Doy - Decimal day of year after 1 Jan 2010. Pwr - Backscatter power (signal to noise ratio) (dB). Vel - Line of sight Doppler velocity (m/s). SW - Doppler spectral width (m/s). Vel_err - Velocity error (m/s). SW_err - Spectral width error (m/s). Freq - Operational frequency (MHz)). |
